Description

Rotary pulsive superfine powder mixing grinder

A kind of pulverizer, especially rotary pulsive superfine powder mixing grinder, what relate to is the technical field of mechanical pulverizer.

Blade of a sword formula pulverizer in the known technology, abrasive disk type pulverizer, its weak point are that noise is big, efficient is low, grinding particle size is inhomogeneous, function singleness, and narrow application range is unsuitable for industrial needs such as chemistry, mine, food, medicine especially.

The purpose of this utility model is to provide a kind of rotary pulsive superfine powder mixing grinder, mainly is to improve the uniformity of pulverizing, and increases work efficiency, and strengthens its adaptability in many industrial circles.

Above-mentioned purpose is achieved through the following technical solutions:

Form overall structure by housing, rotor disk, stator dish, inlet tube, outlet, power transmission shaft, cover, rotor wing tooth and stator wing tooth.

Power transmission shaft (13) is slidingly connected in the centre bore of housing (3), the fixedly connected rotor disk (1) that has wing tooth (6,7,8) of its axle head, again in the fixedly connected stator dish (2) that has wing tooth (9,10,11) of the inner face of cover (14), make its rotor disk wing tooth and stator disk wing tooth, at a certain distance after the engagement, cover is fixedly connected on the housing end face, establishes inlet tube (4), outlet (5), promptly constitute whole.

On the side of rotor disk (1) and stator dish (2), respectively from interior circle beginning gradually outwards at a certain distance, uniform 3～6 row's wing teeth (6,7,8) and (9,10,11) of line-spacing.

Wing tooth on rotor disk (1) and the stator dish (2), be to distribute by certain displacement concentric circles, the distance of adjacent foil between cog on concentric circles, be less than or equal to the wing facewidth degree on the next concentric circles of outer direction, its shift value, be that any a pair of adjacent foil between cog channel cross-section is in open position, the channel cross-section of the wing between cog that any one is relative is in closed condition.

The wing tooth of rotor disk (1) and stator dish (2) (6,7,8,9,10,11) is an arcuation, and its center line overlaps with axial line.

Inlet tube (4) is connected the center, outer face of cover (14), and outlet (5) is connected the top of housing (3).

Thus, many advantages of the present utility model show.

When this equipment of utilization carries out the even phase process of other industry of petroleum emulsification, owing to there is fluid pulse speed, change with the liquid flow path direction, make the even efficient of changing process mutually improve greatly, and the size of emulsion droplet also diminishes, improve fluctuation velocity, also just improved material dispersed speed and dust dispersion quality, because the turbulence type fluctuation velocity is to cause a grain broken major reason in the emulsion process.So equipment is by a circulation, just can obtain to stablize, the ultramicro oil water emulsion (drop is about 5 microns) of homogeneous, dispersion.This equipment of that is to say can be used as Continuous Emulsifier, need not be the pre-emulsification of each component.

The utility model is described in further detail below in conjunction with drawings and Examples:

The ultrafine dust pulverizing machine is a rotary pulse equipment, it is by having

wing tooth

6,7,8,9,10,11 rotor disk 1 and stator dish 2 constitute, wing tooth is arranged by concentric circumferences, each dish all has certain displacement when upward distributing by concentric circles, the distance of the adjacent foil between cog on concentric circles, be less than or equal wing facewidth degree on the next concentric circles of outer direction, pterion on one or several concentric circles in rotor or the stator dish, its shift value will guarantee when any a pair of adjacent foil between cog channel cross-section is in open position on rotor disk and the stator dish, and the channel cross-section of the phase adjacency pair wing between cog that distributes along concentric circles is in closed condition.In order to reach this point, the channel cross-section axle on some concentric circles is coincided with other wing tooth axles that are close on concentric circles that coil together.Also can make the shift value of wing tooth, guarantee that the ratio between the number of channels on each concentric circles equals non-integer or equals non-odd number.

Since in the utility model on concentric circles the distance of adjacent foil between cog be less than or equal to wing facewidth degree on the next concentric circles of outer direction, and the wing tooth on one or several concentric circles in rotor or the stator dish, its shift value will guarantee: when any a pair of adjacent foil between cog channel cross-section was in open position on rotor disk and the stator dish, the channel cross-section of the wing between cog of the phase adjacency pair that distributes along concentric circles was in closed condition.Therefore, it has guaranteed the increase of vertical flow stream velocity fluctuation velocity, and when rotor and stator were in any relative position, laterally the direction of liquid stream can change.The change of liquid flow path direction makes and separates in the slit of solid particle between stator dish and rotor disk that still solid particle is pulverized tempestuously in this slit, and is big more as particle size at this moment, and when the liquid flow path direction changed, their were with regard to easy more separation.The solid that some particle is big more, the time that rests in the strong pulverizing district is long more, and the particle that reaches standard is taken out of rapidly by liquid stream and is pulverized the district.This process has guaranteed that each particle is crushed to needed granularity quickly, so the particle of pulverizing is extremely even, has reduced and has pulverized meticulous possibility, thereby reduced loss (fine grained can be crushed to 3～5 microns).This equipment must be with the surperficial plated with gold emery of rotor dish, to strengthen its abrasion resistance when pulverizing all kinds of ore.

Fig. 5,6, the 7th, stator and rotor arrangements schematic diagram, the structure of this equipment, form by rotor disk 1, stator dish 2, housing 3, inlet tube 4 and outlet 5 on it, on rotor and stator dish, install rotor disk

wing tooth parts

6,7,8 and

stator wing tooth

9,10,11 according to concentrically ringed mode.

The sectional axis that runs through axle center, hole, cross section and

tooth wing

9,10 that must accomplish tooth wing 10 coincides.

Material is through import 4, deliver on the rotating disc 1, because the rotation of rotor disk produces centrifugal force, the material that is stirred is by stator and rotor disk 1,2, move to outer rim along running through the cross section mouth between the tooth wing that is positioned on the concentric circles line, the effect of tooth wing forms turbulation, and because the effect between stator dish 1 and rotor disk 2 tooth wings forms fluctuating velocity, thereby has eliminated the dry run phenomenon of logistics.As long as observe the condition of a≤b, just can obtain the circumscribed minibreak of logistics.At this moment separation (pulverizing) effect maximum.Mixtures of materials arrives the rotor plate edge, just gets rid of by outlet 5.
